Goal: UsernameValidator allows trailing newline in usernames
Description
ASCIIUsernameValidator and UnicodeUsernameValidator use the regex
r'^[\w.@+-]+$'
The intent is to only allow alphanumeric characters as well as ., @, +, and -. However, a little known quirk of Python regexes is that $ will also match a trailing newline. Therefore, the user name validators will accept usernames which end with a newline. You can avoid this behavior by instead using \A and \Z to terminate regexes. For example, the validator regex could be changed to
r'\A[\w.@+-]+\Z'
in order to reject usernames that end with a newline.
I am not sure how to officially post a patch, but the required change is trivial - using the regex above in the two validators in contrib.auth.validators.
## Completed stages
- **setup**: fail
- Script: `git clone https://github.com/django/django.git . && git checkout d26b2424437dabeeca94d7900b37d2df4410da0c && python -m pip install -e .`
- Stdout:
```
fatal: destination path '.' already exists and is not an empty directory.
```
- Stderr: (empty)
## Context
- failure_class: deterministic
- failure_signature: setup|deterministic|script failed with exit code: <n> ## stdout fatal: destination path '.' already exists and is not an empty directory.
Fix this GitHub issue in the repository. Make the minimal code change needed.
